The core principle establishes a deterministic mapping function between abstract DAX summary query structures and their rendered Power BI visual counterparts. This mechanism relies on the formal definition where "category breakdown" represents the Cartesian product of specified grouping columns, which serves as the structural basis for defining aggregation dimensions in domain-specific business intelligence environments. The theory dictates that every row within an engine-generated summary table corresponds strictly to a single glyph or data point in the final visual output, ensuring fidelity between logical groupings and graphical representation without intermediate abstraction loss.
